With whereby the objectscontemplated are ata groove for both the sheathlng and the sidindicatedat 32 and i A by the nails 4L0.

ing a much is provided at the frame A.

As indicated at 26 and 28, groove is provided so that when the windowframe A is applied to sheathing that does not have a tongue, asindicated at 22a, in Figure 5, the portions 26 and 28 may rest on thefiat upper surface of the sheathing 22a for aligning the window frame Arelative to the window opening.

It will be obvious that withnothing but a sloping lower surface to reston the sheathing 22a, any slight misalignment outward or inward of oneend. of the sill would cause the window frame to assume a non-verticalposition, .which' is objectionable.

Instead of providing side and head jambs extending completely from theouter casings tothe inner casings of the window frame, I make the jambssomewhat narrower and widen themto the proper width byconversion strips30. l r

The edges of the strips 30 are grooved as the sides thereof are groovedas indicated at 3%. The rear edge of the jambs 12 and 14 are tongued asindicated at 36.

In ordinary frame building construction where siding is used outside ofthe sheathing, the conversion strips 30 are mounted flatwise asillustrated in Figures 1 and 2 of the drawings, with the tongues 36'coacting with the grooves 34.

The side jamb conversion strips instead of stopping on top of the sill10 as the side jambs themselves do, extend on down past the sill, beinglocated in notches 38 cut in the inner ends of the sill. The portions ofconversion strips which extend into the notches 38 are nailed to thesill as indicated by the dotted showing of the nail 40 in Figure 2.

The rear edge of the sill is held in supported position relative to thewindow frame The outer edge of the sill is supported by screws 4L2 whichextend through openings 44: arranged at an angle from a socket 46 ineach side iamb 12 lower end of the side jainb.

The screws 42 extend into the sill 10 as best shown in Figure 7 of thedrawings. The lower ends of the side jambs. 12 preferably extend intodadoes 48 formed in the ends of the sill 10, so as to properly align theside more effective weatherproof oint bottom of the window jambsrelative to the Slll.

Where it is desirable to use the window frame in brick veneerconstruction of a frame building, as shown in Figure 3, an air spaceindicated at 50 is usually left between the sheathing 52 and the veneerbricks 54.

I have provided a weatherseal 56, consistingofa vertically arrangedboard to overlap the bricks54, and having a tongue 58 to extend into agroove 6O formed in the outside of the side jamb 12. The extra thicknessa level bottom to the taken up by the weather-seal 56 increases thethickness of the wall, and the conversion strips 30 are thereforeapplied to the jambs edgewise, as shown in Figure 3, with nails 40a,extending into the sill. Thus the same conversion strip may be used foreither type of construction as illustrated in Figures 2 and 3, by merelychanging it from one position to another. In either position, theconversion strip serves ing the inner side of the sill.

In Figure 1, I have illustrated the weatherseal 56 and the conversionstrip 30 applied edgewise in a solid masonry construction with brickveneer.

A window frame constructed in accordance with the above description isreadily adaptable to various types of building constructions with aminimum amount of labor in installing the frame. The particular way ofsecuring the sill to the side jambs and conversion strips eliminates allloosening of the sill joint. The frame can also be applied to the newerwalls formed of plaster board or other thin wall material by omittingthe conversion strip or slightly altering it.

The window to which my construction is applied may be of the weightlesstype illus-- trated in Figures 2 and 3 of the drawings or may be of thetype having weight boxes as illustrated in Figure 4. In this figuremembers 62 and 64; cooperate with the side jamb 12, the conversion strip20 and the weather seal 56 to form a weight box. The member 64 may beprovided with a tongue 66 if desired to fit into the groove of theconversion strip.

Screens and storm sash may be accommodated in the ordinary way, the sill10 having a shoulder 62, for them to abut against.

The frame A and the window sashes B and C are easily installed the sameas in present day constructions.

Some changes may be made in the con- I struction and arrangement of theparts of my window frame construction, without departing from the realspirit and purpose of my invention, and it is my intention to cover bymy claims, any modified forms of structure or use of equivalents, whichmay be reasonably included within their scope.

I claim as my invention 1. In a window frame, a jamb having a tonguealong its inner edge, a strip of greater width than thickness and havingtwo grooves, one in its face and the other in its edge, said strip beingadapted to be applied either flat-wise or edge-wise to said amb with oneof said grooves engaging said tongue.

2; In a window frame, a jamb having a tongue along its inner edge, astrip of greater width than grooves, one in its face and the other inits edge, said strip being adapted to be applied either fiat-wise oredge-wise to said jamb with one of said grooves engaging said tongue,said the purpose of supportv thickness and havin two grooves beingequi-distant from an edge and aface respectively of said strip wherebywhen said strip is applied in either posit-ion it will be flush with theinner face of the jamb.

3. In a window frame, a sill, a side jainb, a strip applicable to saidside jamb either flat-wise or edge-wise and flush with the inner face ofthe same when in either position for widening the jainb to a greater orless extent respectively as required, said strip having one side thereofin alinement with the inner face of said side jamb whereby said strip,when applied to the jambedge-wise or fiat-wise, will abut said face.

4. In a window frame, a sill, a side jamb, a strip applicable to theinner edge of said side jamb either edge-wise or fiat-wise thereagainstfor widening said jamb to a greater or less extent respectively, saidsill having a notch with one face of which said strip engages when saidstrip is in either of said positions.

5. In a window frame, a sill, a side jamb, a strip applicable to an edgeof said side jamb either edge-wise or fiat-wise thereagainst forwidening said jamb to a greater or less extent respectively, said sillhaving a notch provided with two faces, one in alignment with said edgeof said side jamb, said strip engaging said face when in either of saidpositions.

6. In a window construction, a sill, a side jamb and means for securingthe two together, comprising a screw extending through the side jamb andinto thesill and positioned adj acent the outer edge of the jamb and aseparable extension member attached along the inner edge of the jamb andextending past and secured to the sill adjacent the inner edge thereofsaid separable extension member being adapted for varying the width ofsaid jamb to suit different wall thicknesses.

8. In a window frame, a sill, a jamb terminating in the upper face ofsaid sill, a separate strip along the inner edge of said jamb andsecured thereto for varying the width thereof and a vertical notch inthe inner edge of said sill, said strip being longer than said jamb andextending past and engaging in the notch in said sill for attachment tothe sill when the parts of said window frame are in assembledrelationship.
